SelectNextControl Causes Radio Button Click Event?
Jun 11, 2010
I have a windows form application built with Visual Studio 2008. When a use clicks a command button which does some action, I use SelectNextControl to automatically move to the next control in the tab order once the action is completed.
This seems to work very well, however, I have recently discovered that if the next control in the tab order is a radio button, the call to SelectNextControl does not simply make the radio button the active control... it also causes the click event to fire. When I use the tab key to move past the command button (rather than clicking on it which will result in a call to SelectNextControl), the radio button gets focus as expected and the click event is not raised (as expected). I don't know if this is a bug in selectnextcontrol or the radio button control.
Has anyone else seen/solved this problem? Another forum post discussed a problem where the radio button was automatically checked when a form was first displayed and the radio button was the first control on the form. Seems to be a very similar problem. That post was from 2008.

I'm curious if there is a "check all" kind of thing for a tablelayoutpanel? To explain, say I have TableLayoutPanel1 with 6 radio buttons and I'm doing an error check to make sure that at least one radio button has been selected during a click event. Do I have to do If / and with all 6 radio buttons? Or is there something like "If TableLayoutPanel1.checked(obviously not this) = false then".

User will use a button1.click to open a filedialog to locate the file they needed. after which, the name of the file will appear on a textbox. Button2 is an OK button to write the filename into a txt file. Button2.click will work with the 3 radio buttons - meaning when Radio Button 1 is true and Button2.click is clicked, the filename will be saved asFile1.txt.if Radio Button 2 is true and Button2.click is clicked, the filename will be saved as File2.txt. Likewise to Radio Button 3

New user here using VB .Net 2008
I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
If radiobutton1.Checked Then
Groupbox1.Visible = True
Groupbox2.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:
If radiobutton2.Checked Then
Groupbox2.Visible = True
Groupbox1.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
The second groupbox does not appear and is directly behind the first groupbox.
The .Top code doesn't seem to be working either.

Reading about VB .NET I found out that now it is possible to handle more than one control with the same event handler. What I want is to specify what my Radio buttons will have to do, using a single sub instead of using a sub for each of them. However I am still far from achieving that. I am using something like that:
Private Sub ForAllRadioButtons_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged, RadioButton2.CheckedChanged, RadioButton3.CheckedChanged
If sender.name = RadioButton1 Then
Code 1 ...
ElseIf sender.name = RadioButton2 Then
Code 2 ...
ElseIf sender.name = RadioButton3 Then
Code 3 ...
End If
End Sub
However, I get an error message which says :
Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.RadioButton'.
I bet 100 $ that it's something that I don't do it right . Unfortunately I can't get that money. Would it be the same if use the Click event instead of the CheckedChanged ?

I have two radio button on my asp.net page, with AutoPostBack = True When I click on either of those, they each set a flag SaveData=False However, when I click on them, the page_load event occurs first, so the page_load event saves the data, then the radiobutton_OnCheckedChanged event is triggered. How can I trigger the OnCheckedChanged before the page_load event?

I have a series of radio buttons in a Group Box on my main form. When I run the program, the first step is Sub New and the InitializeComponent() procedure.
It then immediately goes to the first radio button CheckedChanged event. This even currently contains some programming to access information from a database table. However, the program hasn't even gone through the process of opening the database and logging in. This doesn't happen until after my frmMain.Load event. However, this happens after the CheckedChanged event for some reason. So now that I have included the data requirement, I am getting errors because the reader is opening before the connection opens. I know I can set up a Try....Catch....End Try to avoid a user error, but ...I thought the form would have to load before anything about the controls happens and then since I haven't clicked anything, I am not sure why the event is triggering.

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
